I took my plate off a couple of years ago and then most of the waters we fished went over to wooden platforms or concrete pads... nice for setting a box up on, but utter pants for putting keepnets out, so the foot plate went back on with an accessory bar... course, now I don't fish matches, or even use a box so its moot... but you get the drift...??
If your going to fish with a foot plate, might aswell use the one with it, best and strongest by far.
This is the Octbox Compact Seatbox w/ drawers. (bought because it does NOT come with footplate) I fish natural waters mostly and only fish the pole / whip to 8.5m. The small footplate is solid, strong and compact. Does me fine and suits my types of fishing.
