Momoese, from what I've seen I don't think topping plants will help it conserve energy because the pup will continue to try to send out new shoots. You need to top And then take a knife and carve into that growing bud to prevent it from sending up new growth. I think topping it in a way that prevents it from sending new growth does give more extra energy to the mother plant verses completely removing them for resale or planting elsewhere.
From a little experience, having around only 3-4 plants to a corm does provide better fruiting consistency and better fruit than a mat that has something like a dozen plants. You would think a giant banana mat will year after year always be having fruit or blooming all the time with consistency, but it really doesn't and when there are several blooms, it seems to produce smaller inferior fruits.
