Go ahead and get some 160 RX8s, learn for a year (6 more times
) and then trade up to the right length on whatever is the best for your purposes next year. They are too short, but if you liked the 155s you won't notice. When you get going faster over choppy terrain short skis make it harder to balance front-to-back.
Start thinking about tipping skis and using little effort to guide the skis and letting the skis do the work, like using the reigns on a well trained horse instead of yanking the bit around on a stubborn mule.
I haven't been scuba diving in decades, sold most of my equipment, still do a little skin diving though, not much as it hurts my ears going up and down every two or three minutes.
Do you think my ScubaPro JetFins are still good or is their performance passee? Do those venturi holes really do anything?
