Question about FICM tuning

[TotalDoubt]

I currently already have a Gryphon Evolution with the canned tunes, and I was wanting to order some custom tunes for it. Now, I see I can use it as an FICM tuner. My question is this, would it be more beneficial to use it to tune the FICM, or just get custom tunes and keep it as a programmer/monitor? If it would be more beneficial to just use it to tune the FICM, and maybe get a handheld SCT unit with tunes, I would rather do it. Also, I saw on the website that if you have the PHP Gryphon, they can program the FICM's remotely. How much would that cost, and how long would that take? Thanks so much.
