Never seen a broken slingshot? Jeez, I know one guy who broke 3 circa 13'-16' T rex/Angry Swallow...the ones with the funky graphics. I could probably break one by looking at it the wrong way...
I'll throw in a plug for vendeavours, my Smook takes a beating. In line with some of the comments above, i reckon something with PU blank, thick stringer, full deck pad and a decent amount of glass is hard to go wrong. (I only weigh 70kg - but I do have a knack of breaking boards though)
OK picked up another board... Vanguard is holding up but I'm a bit worried about the fin box repairs eventually failing and becoming a pain. Ended up test driving and then taking home a 2017 Cab Spade, the Cab surfboards shed a lot of weight from the last two years while still feeling pretty strong. This board wasn't really on my radar but I'm glad it was recommended. Fuller outline, fast rocker, but still some good surf-ability. Still frothing to get on a Vader, everyone tells me if I like the vanguard I'll love it. I'll post some follow up after putting some hard sessions on the Spade.
I was going to give the squid launcher a go too, it looks crazy fun...honestly I kinda fell in love with that spade right off the bat so I didn't want to even try anything else. Had a good long powered up day on the Spade today, that thing just wants to jump. I feel like I can always get that rail in too, even really powered. On the Vanguard it would start getting really hard to hold the edge to get a proper load up on the jumps. I'm sure the Vader is killer, more rocker and a tighter tail. I'm going to ride the spade as far into the winter as I can, I am curious to see where it tops out for wave size. Feels like a few feet overhead and under it will shred.
Not to crap on about customs too much, but the difference I've found between a decent custom and a stock board is chalk and cheese. Perhaps it's because they make a production board for very wide range of people kooks and alike, but in comparison, at times they feel like there is something wrong.
I know what you mean bjw, I think a lot of problems with production boards start with the fact that it's not sized specifically for you. I think I've been lucky and ended up on stuff that works for me, but I'm a pretty average size dude.
