Looking for opinions on what brand and/or type of lead or steel weights people have had good success using to add weight to the handle of their racquets. Ideally, I'm looking for something the will fit in the tubes under the butt cap with some cotton wrapped around them to keep them in place. I've seen that some people use fishing weights and I see that there are steel ones available in addition to lead. I would prefer to use steel as handling lead is not usually a great idea, but I don't want to buy steel weights that won't fit into the tubes. I assume the steel ones are bigger to achieve the same weight as the lead ones. I'd also rather not use lead tape in the handle or under the grip and I'd like to have a system where I can remove and insert different weights until I get the racquet weight/balance that works best for me. Thanks in advance.
