I'm thinking single pole. I do like the look of the bass tracker 175 and have seen some used ones pretty cheap.
i have the 175 tf. its made for crappie fishing and shallow water, the reason i bought it after selling my skeeter. perfect for how i fish which is a lot of backwater off ky lake. i can fish the main lake as well but you really need a 70-80 lb trolling motor but if the wind gets up its still a chore, although it does ride good even in rough chop.
the problem with the trackers. they are under powered except for the 190 and 195 with the max motor on them. if you can find a 2010 175 they were rated for 115 hp. i dont know why for that one year.
i dont know how big you are but 3 above average size people in a 175 even with a 75 hp is going to be a push and you need to have the 4 blade prop on it to get on plane.(the newer models have been coming with 4 blade upgrades)
i dont know how they figured person weights on all of those trackers because the USCG is 180lbs per person but all the trackers are rated for 4 people but only 575 lbs people weight for all of their models, even though they are almost the same dimension as a G3.
fishing by myself is fine but when my son fishes with me he sometimes throws me out of the boat when he shifts from one side to the other. he weighs about 225 lbs.
i like the 175 but i wish i had bought something different since my son and grandsons figured out fishing is fun, lol.. i looked at the 190 g3 but even though its higher rated it has a 4" less beam width than the tracker. so i imagine it would be tippy as well.
hope this helps
