I had a waterworks 2 on my 4wt and the leader would get between the spool and the black piece (not sure what they call it). They are great looking reels that are super lightweight and they put a guard on the saltwater models to combat that problem. I have owned 3 lightspeeds that I never had issues with FWIW
The ULA Force is a sweet little reel. I have one and used it for guiding this summer and it worked great, just as it should. I never had any problems with it and we had lots of fishing pulling on it. I have a 4wt line on it and even with the line and backing on it, it feels so much lighter than other reels. I put this on a Hardy Zenith and the thing is super light and hot looking! Not that the clients know any different though.
