g52...I find up here in New England ponds, the bass will be on the edge of the thick weeds during a stable condition. If a front is in, then they will tuck under. Despite being "book taught" that the bass will tuck in the weeds during a "blue bird" day, I'm finding that bass are still out on the weed edge at this time of year on a pond here and will be active. The bigger boys will be out further from the bank adjacent to deeper water and the little guys are around the bank. You will find some bigger bass at times shallow, but they are very finicky.
I'm mostly a bank fisherman during the week. I try and get out about 3 times a week after work and my advice I just gave you is based on what I've been seeing thus far. This is clearly MHO.
I've been making long cast to the outer weed edge with a 1/4 oz jig and chunk trailer or a 3" or 4" grub. The average 2 hours I fish for will yield 4-6 nice bass from the bank.
I also find that on a natural pond an arky jig works really well. In man made ponds/reservoirs I tend to lean towards a flipping or casting jig like a Strike King Bitsy jig or Bitsy Flip.
If you really think that the bass are holed up in the thick weeds and you can't cast past the edge, then a 1/2oz is what I use, especially during those days when the front is in. If you can cast past the thick stuff and work your 1/4oz into it and thru it (don't be afraid to lose some jigs), then I find that's the way to go.
Please, take this with a grain of salt, but here in MA, that's what's been working for me.
Good luck.
