fortunate enough to have used majority of the boards being discussed and agree for onshore lightwind days longer boards are better. so is a much flatter rocker.
uphauling for me is more about volume. i have a 71 wide 125lt board that i struggle to uphaul unless it's flat water and a 66 wide 135lt board i can uphaul in small surf. also have a 9'8" x 33" wave sup that's easy to uphaul too. longboards also easy to uphaul.
one of my mates uses both the LT and the Kona's in small surf. whilst he prefers the Kona's for surf he uses the LT without complaint.
horses for courses. both good in different waves. one surfs like a log and the other is more like a funboard.
neither are like shortboards. guess thats why we have so many options.
also don't agree that sups don't plane. maybe that's another option. especially the older models. i have some older fanatics that are great. my custom sup doesn't plane so good but the shaper has a ducktail version that planes.
