i have basically shot all the different timmys and angels, i also own a trix & a viking
a-4 fly w/j&j edge kit, 4.0 software, mastertech trigger, centerflag 68 4500psi, blah, blah, blah, all the goodies basically
different trigger & trigger guard (the chain guard should be a felony to use & bob long should have a few fingers smashed for that atrocity)
maybe some new grips, the stock ones feel pretty crappy.
Accuracy, air effiency, speed.
Construction, the barbs are made like garbage.
i shot this marker in 5 tourneys and over 25 practices, it never breaks paint, and is very fast and fairly accurate, it gets great air effiency (i averaged 6 pods and a hopper off a 68 4500psi fill) however my marker had it's fair share of bugs, it came with the barrel milled into the body incorrectly (it was stepped up almost 1/16 of an inch between the barrel and the breech) it caused a lip internally that caused just about every single ball to smash. but Bob Long made good on this issue, i sent the timmy back to him and they replaced the body free of charge (which they should have). it still leaves a couple of concerns open in my mind, but that is unfair to gripe here. i think the marker performed excellently, after the issue was taken care of, it is very fast, good on air, light and seems to be pretty reliable so far. it's accuracy varied a little, a good barrel kit should take care of this problem, seems to perform much better with a good bore to paint match.
Good marker, high priced, but what isn't? I found it to be very fast, good on air and aside from the issue mentioned above, very reliable. I would recommend it highly and pray you don't get a lemon like i did, but big thanks to Bob Long for taking care of the problem, but imho it shouldn't have ever left the factory with that obvious of an error. But i do recommend this marker, good buy and mows faces for sure.
