I have a puma ftd with 250 pro xs and dual PP. They are 2010 model so probably heavier than the blades.It did hurt my hole shot some and top end about 2 mph. Like dr jag I went to a 25 p fury prop, On Lanier here I seldom am able to WOT due to pleasure boats anyways.When I go to guntersville or lake like that they are valuable,On lanier I use them at the dock, Still tie up but push boat away and lower the poles, Waves here are bad so that keeps boat from banging.I fish tournaments solo sometimes so Ill dump my boat and once it floats out Ill lower the poles (need remote control) then catch a ride out with someone else. Lunch time in summer I;ll find a shady spot on shore, anchor and we eat our sammiches (as K Short says)If were out for fun and go swimming Ill anchor boat on sandy beach.If I want to stay stationary on a deep point and wind is blowing with waves Ill lower them and that helps steady the boat.If I want to fish along a windy point or bank Ill lower them and that slows boat down and just steer with the TM.My mechanic is not very fond of them though.
