canoeing leaves means it's too hot
and topping does give you more bud sites, normally, but that's with a vertical grow, one topping and you get double the bud sites
LST with topping could do the same, depends on what you plan to use the topping for
it seemed that it could be used as a safety measure, making sure you don't get the plant extending to far around the pot
if you want to LST and top to get even more bud sites, i'd recommend just LST, it's much simpler to perfect 1 technique at a time, but it's your call
