Body glide is definitely the best option and when putting it on your neck make sure you get all around the neck, especially the back. I agree that tri shorts are very helpful and I hadn't heard the tip about running gloves - GOOD ONE.

Long sleeves are great. it used to be that people tried to get away without long sleeves if they could because of the restriction of movement. But now the materials are so much better that you get full arm movement in a long sleeve and it's really nice to have the added warmth.

The biggest fit problem that I have is around the ankles. If the ankles are too tight, it is really hard to get the suit off quickly in transition. So check that out carefully. I had a suit that I took in to be altered to lower calf length in stead of ankle and that worked really well.

Have fun with the new toy. You'll love it.
