Regardless of rim, you should strongly consider 36h. You’re not a racer, I promise you won’t notice any increase in weight going from 32 to 36. But you absolutely will notice a stronger, stiffer and over the long term much more reliable wheel. I’m right at 200lbs myself and I have hplusson tb14’s 4x laced 36 spoke wheels and they are probably the best wheels I’ve ever ridden. I don’t go easy on them either. 36 will absolutely make a difference and is absolutely worth it. You want reliability in everyday performance? You concerned about your weight and it’s effects on that reliability? Then heed the advice, do yourself both a practical and financial favour and build or buy a 36. A 32 might be perfectly fine for the front, but a 36 for the rear is a wise investment, and a 36 set front and rear will give you a wheelset you can rely on for decades if not longer.
