Will single-wall rim be good enough for my road-use?
I'm thinking of building up a rim-brake rear wheel with a 16"/305 rim and 36 spokes. For the rim I seem to have two choices (after canceling out some excessively-wide BMX rims) :
1. Weinmann 519, which is single-wall, inside diameter of 19mm and overall height of 16.3mm.
2. Alienation Blacksheep, double-wall, inside diameter of 27mm and overall height of 15.8mm.
The tire will be a 50mm road tire, inflated to probably no more than 35psi. Rider weight will probably not exceed 140 lbs. Would the single-wall rim with 36 spokes make a wheel that's strong enough for on-road riding (sometimes on gravel)? All of the bicycle wheels I've ever owned/used had double-wall rims.

Is the cost of the single wall prohibitive to you trying them out and trashing them if they don't work well for you? To me, trying something is the best way to know what works for me and what doesn't work.

Maybe it's my lack of skill, but I always struggle more getting and keeping single-wall rims in true than double-walls. Maybe 36 spokes will help.

First of all, I have to guess because your dimension info is nearly useless (16" wheel?) and you reference diameter when I assume you mean width.
That said, and assuming I'm guessing right, I suggest you go with the wider rim. Not because it's double wall, but because the width is a better match for the tires you plan on using.
FWIW if this is indeed a 16" 36 spoke wheel, it's already overbuilt so rim strength will not be an issue.
