Afraid-very-Afraid

G'day to all,
Sorry Fellas; it might be advisable to get out the popcorn and settle in..this could be long
Afraid-very Afraid is what I am when things require upgrading over the internet from downloaded files.
I say this because of my own experiences and the multitude of disappointments and frustrations that I read on this forum and many others concerning this 'downloading and updating' business
I have had a Evo2 Dash pod programmer in my 2003 7.3l for a couple of years and have never (r) never been tempted to check for updates. In fact I turned the Fusion Disk into a 'Bird Scarer' for my fruit trees soon after unpacking it from the box.
Being a diesel mechanic in a former life, I have no problems getting mechanical and swing tools and doing mods as can be seen from my sig.
I have just completed the last of the performance enhancement mechanical mods I intend doing. And that is fitting a John Woods Valve Body (JWVB).
Before fitting the JWVB I had been running the Evo on the #1 (Tow Safe) setting continuously and with the custom 'Shift Firmness' set on +6. It towed, drove and shifted well and I had no real issues. With the JWVB the Custom tune for Shift firmness is set back to zero.
However I always intended to get proper custom tunes when I finally completed my mods.
I have come up with a number of questions, so I'm asking for any advice on which way to go.
1. CTS: If I upgraded to the Gryphon CTS my Evo would become a paper weight. However already having the dash pod, I would get the CTS Adapter and mount the CTS in the same position. Also I believe I can still plug the EGT Pryo probe and continue to read EGT. So a CTS + Adaptor + 3 x Custom Tunes, I'm looking at around US$750.
Bearing in mind I have not updated my Evo, what more 'useful' features are now available on your Gryphon CTS (maybe monitor fuel pressure + +??). If I went with the latest and greatest Gryphon CTS and never ever download updates would I miss anything useful in the future?
2. Phoenix 6 Pos Chip: I realise that if I fit a Phoenix, I can set the Evo to stock and monitor essential parameters and lift DTCs and select a custom tune on the fly. With a modified tranny (JWVB) I'd be looking at the US$550 Phoenix 6 Pos Chip. Although a much cheaper option, cost is not the issue "at all".
Also being able to shift on the fly or taking some time to programe the truck for what lies ahead is no big deal to me, convenient yes but not a big deal.
I am presuming that the Custom tunes made for a particular vehicle on either the Phoenix or the CTS are "exactly" the same?
So what I am really asking here is: If cost is not your issue, and you've narrowed it down to these two for the reasons stated: Which way would you go?
Cheers,
Reg.
