I have a Tsunami and it didn't break the bank. I use a TSAWSS1002MH for walking the beaches. I know everyone on the internet theyre are all about the CTS and Century rods but I didn't want to spend that kind of money. The Tsunami went for $100 and I am happy with it. Not as hardcore as the rest of you guys but it works for me. 2-4 oz, 10'. I think if you casted 4 oz all the time you might break it. Does seem to be good for the 2-3 oz range.
If you want to throw eels you might need a mh rod but that will put more strain on you as you mentioned injuries. I don't like the whippy rods either. I use a smaller Lamiglass 8' for places like the cape may jetty and when its very early spring or late fall and only small fish are there. My .02 hope this helps.
