Default which pistons?

I have to change the pistons on the 1980 Shovel 80" +010 l, kick and electric start.
Cylinders are ok, now I fit wiseco 4293 +010.

What do you recommend.

I'm not looking for particular performance and I don't want to break my leg with the kick.

I found the Drag Specialty pistons: REPLACEMENT PISTON 1340CC 3.498" OVERSIZE +0.010" 8:1 PISTONS 80 1340CC 010 Reference: DS750721 for 100€ (106$)
Anyone mount them?

o KB HYPEREUTECTIC REPLACEMENT PISTONS Suitable for 1340cc/80 cui.
Shovel headaluminumOver-/Undersize: +0.010"Stroke: 4-1/4"Nominal Bore: 3-1/2"1340 cmłCompression: 8.3:1USAGross weight: 1.25kg€250 ($265)

My pistons are still ok but I can't find the piston rings for wiseco 9293, or rather I can't find them in Europe and between cost and shipping and tax, I spend less to buy new piston and ring.

The Drag cast pistons, too many potential issues with the KB's. They are very sensitive to sizing and fit in the cylinders and the skirts will scuff up quick if it's out or you don't do a religious easy by the book break in period.

all the racing pistons have 4 on each piston as they double them both sides - never seen one fall out but they are asking sure it wont
