Ok so I had my 98 custom for 5 months or so and decided to order the double trigger and response trigger from actionvillage. At the time I had not yet ever opened up my gun so I was going to install the RT with my friend the next day but I planned on installing the Rufus Dawg Double Trigger the same day.
So I opened up my tippmann for the first time and the trigger was really easy to install, so I put it in and attached the new trigger gaurd put the gun back together. So I decided to try it out. I wasnt sure what to expect, I wanted a trigger that I could walk but let me warn you, this trigger WILL NOT make your gun have the trigger pull of an electric gun. Let me repeat that, it WILL NOT have a light pull like an electric gun unless you do a certain mod or have a custom pro (Im not sure though) but with just a 98 custom you cant walk it. However by being able to fit two fingers in there its a lot more comfortable, if your out on the field for 8 hours you fingers are a lot less tired with the double trigger.
This is a decent product, but for me its only high point was the comfort, if you want to shoot 10 BPS with a 98 custom I recomend the response trigger, this trigger is nice because it works with the response trigger. I'll give this a 7 out of 10, would be nicer if it was made of metal or aluminum.
