I'm not certain I understand your post, but I believe you are saying that you have both a BoomKicker and a topping lift
, and want to discontinue using the topping lift. Pardon if my reply underestimates your sailing knowledge (no offense intended). These two do not "work against each other" as they both lift the boom. The boom vang
works against the BoomKicker by pulling the boom down, which may be needed when sailing off the wind
as the main sheet is at too large an angle to pull the boom down.
I replaced the topping lift on my 22 with a BoomKicker, which is sort of a poor-man's rigid vang, to avoid playing with a topping lift while single-handing. I think it was an improvement in ease of dropping the main, and in allowing some boom lifting during sailing (you don't use a topping lift during sailing). I know they make sizable BoomKickers which would be appropriate for a 33, and encourage you to use one. The topping lift may be retained, or re-rove with a larger line, and kept as a spare at the mast
out of the way. My philosophy is that you can always use another halyard
