Got my guru 3 the other day in the mail and thought maybe it was a little small in size bit I didn't think I needed the bigger 3.5 for silvers , bows , chum and pinks and I thought the more compact the better for fishing all day everyday for a week on my next trip .I put a full spool of 20LB backing on ( 100 yds ) and my 30 ft flyline , it barely fit , I'm not sure if I get run out real far if it will reel in without hitting the line . I have a helios in the same size and wanted a back up and the better drag on the lamson . I guess the only thing I might have trouble with would be kings and there is the possibility of fishing for them back east but only one trip or so a year . Should I keep the smaller reel or get the 3.5 , I could take some backing off and maybe even a little flyline if needed .I'm fishing an 8 wt. rod.
