The only time that I've needed to use a high tack tape was when I did a matte vinyl for an art show, all other times, regardless of 651/751/951, I've used medium tack.
You feel more comfortable with the clear, and that well and good, but just remember what some of the other responders said, clear will NEVER stretch, so trying over a compound curved surface and expecting some level of everything being able to lay flat is highly unrealistic.
And for the record, I can't say that I have ever squeegeed through application tape, whether it was paper or clear.
Good luck.
