would be a lot more length/volume than i would want in small waves.
I shaped a mini simmons sort of similar to the puck last spring and it is 5'6" x 22" x 2 3/8" and still has a bit more volume and length than i like in small waves...i would go 5'4" and no more than 2 1/2" thick to avoid that corky feel.
another option for you is the Christenson Ocean Racer. i know they sell them in a few shops throughout NJ. they are a bit more than the bing's, but most shops will knock $50 off or so if you ask them. im 6', 185-190 and i got a 5'8 (dont know the length or width off the top of my head, but its the minisimmons-esque shape). im definitely happy with the dimensions on that. offers good float, but not too corky. i rode that thing all summer up until around september and it made some days pretty damn fun. i rode it from about knee high to head high. on the steeper days it got tough, but it is such a different ride than im used to from my shortboard and that made it fun
I just picked up a 5'10" Bing Dharma. I am 6'0", 165 lbs. I have only been surfing 6 months on an 8 ft. board. I thought it would be a major transition, but I was up and riding it within an hour during my first session. I was using it on 2 ft waves, so it definitely works in small conditions. As long as you position yourself correctly, it's actually almost as easy to catch waves on this as my 8 footer. I also considered a Puck but I think the Dharma has a much wider performance range. If you've got a bunch of other boards, maybe this isn't a consideration, but for me, this will probably be a one board east coast quiver. This board has already exceeded my expectations and I can't wait to see how good it will be once I put in a couple of months on it.
My two cents is if you plan on waist high and under, dont get one with glassed in keels. My other Mini Simmons that i've had for two years is a twinnie and it felt like way too much fin (with the Rasta Keels) for doing quick little turns on small waves, but luckily i have boxes and quickly replaced the keels with little upright fins.
I bought the Swee Pea last spring and it has been my "everyday" board here in South Jersey. I am 6'0 200 and went with the 6'10...a little big but wanted something that still caught waves easily especially in the winter with rubber on. It does not disappoint. It really gets through the mush and cuts back good (not great). It definitely replaces my log and is not one of those boards that will only get pulled out for trips or hurricane swell. It is based off the mini simmons...cool video of it here: Bing Swee Pea
