I don’t think I can agree with 3 sets. I’ve had skis that really came alive with the bindings around 1/4 forwards. I won’t touch a fin until I have the bindings where they feel best and that can take me quite a few sets. I usually will do factory, then I start going forwards with the mikro-just tooth by tooth but for some skis that can take a number of sets to reach ideal. Once I think its best I usually will try a few sets back at factory to verify its better and not just me.
@joel have you tried the Fin DB app? sometimes people will have their numbers non-slot.
Now for a caliper rant.
Slot vs regular should be .03 off so a .730 slot should be a .700 non-slot which is stupid, the whole slot-caliper thing is stupid. Firstly selling you a “precision caliper” with a slot ground in it so that you can get your measurements closer within .0005 apparently on a measurement - but then build it with a crappy 30$ type caliper like harbor freight has so that your 150$ tool now doesn’t repeat to .003 over 7 inches. Try it sometime grab a slot caliper zero it then open/close it 3 times - what does it say now on your zero?
Secondly because if you look at Goode’s manuals and compare their numbers for skis pre/post slot caliper take the 9800SL for instance. Regular measurement DFT .711 Fin Length 6.871 Depth 2.449 and compare them to the slot measurements DFT .741 Fin Length 6.937 Depth 2.453…
Wait what happened here? DFT sure that’s different you’re using the slot vs. the end different technique. Same thing length you’re now not doing tips at the fin box you’re doing jaws across the tunnel that should be different. Depth though? Why is Depth any different? Well because they ground the caliper so when you close it fully it is “more shut” than it should be. So when you close the jaws and zero you are now really zeroed shorter. So they took a measuring tool and made it no longer give you actual measurements just to improve your DFT measurement? Which I don’t know about you but when I do start moving my fin the DFT is the first and usually only one I change. Ok rant over.
