Thanks for the input! yeah the 7 isnt a standard size which also worries me a bit, almost seems like it would be the best of both worlds between the 6 and 8 ya know?
I got a 7 inch mora plenty of pike/walleye came threw it crappie etc.. that's what I would suggest cause you can switch it to laser blades.. after modified the laser blade adaptors a little.. the ones they sell on ebay.. then it cuts like a nils.. if you can find a off set handle.. don't even want to explain how crazy fast they cut with a electric drill with the laser adaptor..
by the way they don't make a 8 inch blade adaptor so plan for future use is my suggestion.. if you switch the blades to laser.. if you go 8 inch mora that's fine to cauae you said your using a cordless drill and it will cut nice out of box. Mora /dtills are way to go.. just won't get as many holes or fast as a adapted mora to laser blades
but remember you can't convert a 8 inch mora to laser blades.. no one makes adaptor.. the adaptor are found on ebay for around $35 if you don't get it this season there's always next season?? Converting to laser blades you will get more holes per batteries... now if you just buy a 6 inch laser it cuts great out of box with hand or drill but pike and walleye forget it.. you go to a 8 or 7 inch laser I would fear the auger might jam up at bottom of hole and wreck the gear box on the drill..
now with a 7 or 8 inch mora it's designed different the cutter heads are so it don't jam up.. then you throw the blade adapotor on and it cut that much better the mora does.. but only can be done on the 7 inch mora..
Oh ya laser blades you can sharpen your self with a smith sharpener and some lansky curved blade stones.. the sharpener holds or clamps blade and stones are held at a angle to blade by clamp.. you need a 30* plus angle to sharpen or hone auger blades that's smith clamps lansky is set at 25*.. mora and laser blades sharpen on the smith clamps just a heads up and it's easy to do..
Any how get a spare set cause no mater what you do it's good to have a back up..
