Yeah, kuiu is frustrating. I'm a 34 in all jeans but generally wear a 36 in kuiu. 34 kuiu seems a little tight all over. The 36 waist is a little big but works for layering and seems to fit better in the crotch. I agree about the size scaling from 34 to 36. Additionally, I've had to sell some 36...
Lapponia would be a good choice for your intended use. Summits seem to be geared more for mountains. I liked them but the rocker is more agressive and they have a tighter toe box. Altitudes are a good mix of the two but they didn't agree with my foot and put pressure point on my toes.
This is rokslide, we kill everything with 223 and 6mm around here, don't ya know?
Kidding aside, killed 2 bulls with 6.5prc and one dropped, the other went 20yds. It is more than capable.
Edit- The bull that dropped was shot with 143 eldx @2900, the other shot with 140vld @3000fps
Mine via the impression box are wider than that. Can you feel the gap? I suppose it’ll be fine since the heel isn’t shifting but maybe give sheepsfeet a call to inquire?
