Hi all

Just thought I would add this to the mix.

One of the guys I shoot against is running a titan No7 in his tx with good results.
I shot it & it felt very fast but a little harsh for my liking, all other internal details he seems reluctant to divulge.
Have any of you tried one before I waste my money.

Regards Jon

I tried the 9 in my set up & it made power very easily, so much so I had to cut a few coils off.

With minimal top hat the spring has only 5mm preload which gives me 11.2-11.3 f/lb.( also gets a bit stiff to cock towards the end but not excessive )

The number 10 had 47mm preload to make 11.2f/lb

I use the No 9 and the Mk2 in my guns depending on stroke, the No 9 is good and makes power easily but is a bit stiff to cock, I would like something in between ideally

I was a bit concerned that with so little preload that it would not keep the bounce in check, but it seems to shoot fine @ 25 yards, of to test it out to 55 this morning.

Mine( TX200) has a very light piston, and that does not bounce with the No 9, I do have a bit more spring room than standard though.
