Chaps I am in a quandary. Which 1 of my 2 wineracks will be better in .25"? Which would be better in .177"?

I appreciate that each will require tinkering and fettling to get them shooting well. I was thinking that the HW80 would be .25" but now I am thinking it might be nice as a .177"????

Help my indecision!
Rich.
