Here's some general info you can use to guide you, especailly with regard to wheel flex, since you mentioned it as an issue.

Spoke quality, and tension do not affect wheel flex, though they can affect life expecancy.

The main thing that affects wheel flex is the total amount of steel, ie. spoke cross section (main length section is what counts here, not the butted ends) and the number of spokes. The bracing angle (CTF distance in hub) also affects rigidity, but less than most people believe except at the fringes, ie. below 18mm or over 40mm.

Rim rigidity counts 2 ways, deeper section rims deflect less radially, and spread load changes better, and so can work effectively with lower spoke counts, whereas shallow rims work better with more spokes. Greater rim width likewise improves lateral rigidity, by spreading deflections over more spokes. More width can make a big difference in the lateral rigidity of low spoke count wheels, but the trend is to narrower rims so, nice light, but slightly wider rims are scarce these days.

Overall strength is determined by the amount of steel at the weakest point, (usually the elbow) but wheel durability improves when the elbows are reinforced with respect to the overall spoke cross section (why butted spokes are generally preferred).

I hope this helps you look at options and form conclusions about what to expect. Good luck in your wheel search.
thanks for all that info, really puts things into better perspective.

think theres any benefit from the wheels below over original Bontrager at-750's....even if they weighed the same? Im considering these at the moment....
