Yeah, I smell what you're steppin in. Since roofies are slightly lighter, if you can afford to spend enough to get the glass quality you need (probably at least $250 new / $200 used), then yeah, I'd agree that going to a 40-43 objective size is probably worth it, even with the weight, for the extra light - still I'd pick a 7 or 8 power for woodsy areas and an 8 or 10 for mixed to open terrain. But over 50, don't forget that every ounce matters. I do go in pretty far though, so it's a big calculus of age, fitness, and how far you're going in. If you're going in 5 miles or more (which is archery season for me), at my age, every HALF ounce matters!

Bottom line, a roofie in the 8x42/43 or 10x42/43 in anything in the quality range of over $250 new (assuming you're not shopping at cheaper than dirt) is almost never a mistake. You could write pages and pages on exactly which makes and models, so not going into that here. For going super light for the woods, especially on a tight budget, a porro or roofie in the 6-8x30-32 range, over $110-$120 is almost never a mistake and will do what you want it to do, almost certainly. I like to have at an exit pupil of at least 4mm (calulated as objective divided by magnif).
