Thomas asks…What is the first trick I should try on skis?Ok, so I’m wondering what the first trick I should try on skis is (beside grinding a rail.) I was thinking a 360 or an Iron Cross, I can’t do a 180 because I don’t have twin tips… Any suggestions? answers:I do 180′s any time and it is not the twin tips that are required. It is balance and limber legs. Twin tips are only needed if you are landing in soft snow and the tails dig in. You can slow your speed and do them on regular skis. We’ve been doing 180′s for more than 40 years and twin tips are quite recent.Mary asks…what type of throttles do jet skis have?My dad shattered his wrist and the doctor said that e would never be able to ride a motorcycle because of the twist throttle. we were planning on buying jet skis. Is a jet ski throttle a thumb push or twist. if it is a twist can you reverse thottle it so that its on the left? thanks soo much. answers:Most, but not all jet skis have a thumb operated throttle. Depending on the year/ model, some can be turned around to allow for fingertip operation. If you desire a finger-operated throttle, and the stock throttle lever
