I install GRT-4G TRIGGER on Gamo Hunter Extreme Ultimate .25 I super polish all the friction contact points and I apply super light thin coat of grease. Result over 80% smoother, over 50% lighter trigger pull and increase accurate whole lot.

I just learn something today I didn't know you could uncock the gun with this trigger.
Not sure what "trimming" encompasses but I've needed to dress the ends of the three Titan springs I've played around with - one was very poorly squared, one was squared a bit less poorly and one was pretty nice and only needed a minor touch (the one in the FWB Sport). No problems doing that on a simple belt sander with a modestly aggressive grit, maybe 240 when it.was fresh? Just guessing on that. Didn't allow the area to build any noticeable heat by only working it for a couple.of moments at a time and dunking it in water every tine i took it from the belt. The whole process took a couple of minutes and I took my time. Finished within my 10 minute break at work.
Well, I'm just guessing here Yogi, but since the 97 & 77, plus the 85/95/98 are so similar I'd say that whatever the results are for my 97 would be replicated in a 77, and that the results would be almost the same for an 85/95/98.
I have limited experience with spring swaps, so I generally find out what the OEM dims are and calculate its spring rate. I do the same for whatever springs I'm considering, so that I have some sort of decent guesstimate on how much I'm changing rate. Of course that's not the only thing that matters, but it's nice to know. In a perfect world, we'd always have springs available that only needed 20% compression to provide almost instant extension and would never fatigue. Wishful thinking.
I recently wanted to down tune my FWB Sport but i didnt want to lose much velocity if i could help it. It got a Titan #4 with a Vortek HW80 seal and a snug delrin guide.. A little less spring but it nmakes as much power now as it did before the swap (14fpe). I basically copied the common fix of removing 1 or 2 coils from the OEM spring, I just did it with spring selection instead of a torch. it's easier to cock and has much better manners than the way it.left the factory. Firing cycle is still quite brief but it "stops" better, if you know what I mean.
I'm going to end up doing the same thing with the 97k, but the goal will be to have OEM velocities without buzz/honk. In fact, if I had a good OEM spring I'd simply use that. I tend to buy Titan springs because they're made of quality materials and I can find good dimensions on them. Very helpful when you're long distance mixing and matching.
Agreed to the quality of the metallurgy in Titan Springs. However, that technology makes trimming the ends more difficult.
