I Have A Question For FX Impact M3 Owners

My question is this:
How much of a performance difference is there between a gun with a power block vs a gun without it?

I want a M3 and many nice guns without the block are coming up for sale. I am not a big long range slug shooter and currently have a MKII Impact so my thinking is if I am going to go with a M3 I should get the power block version.

Just thought I would get some factual opinions.

Thanks
 
I have a 700mm non-power block M3 in 22 cal with no power mods. I have gotten 25 grain slugs to 1030 FPS with the 2nd reg at 125 bar & that works for me. I don’t really want to get heavier with projectiles, pay more for them, & degrade my shot count. If you want to shoot heavy slugs or a big caliber maybe you would want the power block.
