Several different drops, none really compare to this as the upward angle is unique.

Perfect shoulder rest, frees trigger hand for faster walking.
May have trouble mounting certain ASA's (see review.)
I purchased 2 of these drops, one for each of my markers.
After hours of searching online to find a straight drop forward with no downward angle that could clear a nitro tank setup, I stumbled on this drop and it looked like exactly what I wanted. I didn't want a drop that angled downward because I hate having my elbow cocked out (been tagged there a few times,) so I was looking for a straight drop because I like using the butt of the tank as a shoulder stock. Problem was, most of the straight drops that I looked at seemed to be engineered for skinny CO2 tanks and it didn't seem (to me anyways, but I could be wrong) that it would clear a fat Nitro tank. Anyhow, I just happened to stumble across Fireball Mountains website and saw this thing and fell in love with it on the spot. Just what i was looking for, lets me rest the tank on my shoulder AND drops the whole marker setup down for a lower profile.
Ordering from their website was fast and simple, no problems. Order arrived in 4 days.
The fit on my DM5 was perfect, no tweaking or new macroline needed, straight bolt in, removed the ASA, screwed in the drop, remount the ASA, done. Friggin love it! Angles the tank up to rest on your shoulder, while bringing the whole marker & hopper setup downward (fewer hopper hits!) Moves the balance point of the marker setup forward to keep it more centrally balanced, although its not perfectly balanced its much better than stock (anything helps with these fat heavy nitro tanks.) Actually the balance is sort of a moot point now as you can rest the tank on your shoulder and free up your trigger hand to walk the trigger faster using your fingertips than you could by having to support the marker with a death grip with your bottom 2 fingers and thumb.
The fit on the Ego was a little of a challenge. The fit to the bottom of the marker was perfect, straight bolt on, no problems. The problem started with the rail end. The ASA included with the Ego (the OOPS) has this funky inward and upward curve on the mounting rail towards the back of the unit, the rail doesn't go all the way from front to back (Ego owners will know what im talking about.) I had to do a little grinding on the drop itself, almost 3/8 inch at the back to get it to match up to the Ego ASA. So I get the back to fit, then look and the front of the drop rail sticks out too far and interferes with the OOPS knob, more grinding, about 1/8 inch on the front this time to clear the knob. Ok, so now everything fits, except the macroline.... too short. New macroline. After all that, the drop fits perfectly and feels just like the drop on my DM5.
If you have an Ego, I would recommend that you buy the stiletto drop with the built in ASA. If you cant live without your Ego OOPS ASA and you have access to a bench grinder and have a little grinding skill you should be fine too. Third option is to use another ASA, the Dye ASA that comes with the DM5 can be purchased separately and fit perfectly on the bottom of the stiletto.
I don't believe that the problem was with the FBM drop though, I think that this problem was specific to the Eclipse OOPS ASA. Other ASA's shouldn't have this problem. Any ASA that has rail cuts that go completely from front to back should fit fine. The design of the rail on the FBM drop is great, actually its long and affords you more options on weather you want the ASA further forward or backward.
The only real downfall I can see is that with the way the tank is angled your ASA becomes the lowest point on your marker setup, if you're not careful you could bang your ASA on the ground if you're diving or crawling (maybe that's not a downfall though, last time I checked ASA's were cheaper than Nitro tanks.)
I recommend this drop to anyone that wants to reduce the profile of their marker setup. Also recommend this to anybody who likes resting their tank on their shoulder. The angle of the tank is perfect for this. Anybody with a DM5 should get this drop, it balances the marker and makes it easier to get ropes walking the trigger. Also recommend for anybody with an Ego, if you're willing to do some work. If not, just buy the stiletto with the built in ASA. Innovative product. Try one you'll love it. I give this product a 10 even though I had trouble with mounting the EGO ASA, it wasn't really their fault though. They were thoughtful enough to have an alternate product that could handle such problems.
Hey great review, u gave me so many new points i can say to my doubting teammate that keeps telling me not to get it, and seeing that i'm a back man, i usually only dive when i really have to (once a month with my good gun) and if you would have just bought the stiletto with the ASA on it already it would have been easier... but then again its like 10 bucks more and u did buy two of them, well anyway i just wanted to say thanks for all the good facts
