I moved the vibra blocks down to the limb pockets and put on limb savers.
Also the hush puppies came off so I put on cats whiskers cut to about the size of 1/2 dollars pushed right up to the shrink tubing.
Cant comment on your speed as mine is a 60#er @ 28"
I am getting 275fps with a 385gr arrow and 288fps with a 345 gr arrow.
Oh I forgot 283 with a 353gr arrow
