Thankyou for the prompt responses guys.

I inspected the neck again this morning, as I was going to take a few photos (Thankyou for the idea Brendon).
But I was unable to get a photo showing any significant twisting.
It seems to have stabilised (if that is even possible?), but in any event the twist is less than I originally observed/thought.

So I will opt for Option 1 and have withdrawn my support request to Pitbull.
The heel is an excellent fit to the body and as you say Simon, it would be difficult to get a replacement that exacting.

So, I will go ahead with this one and hopefully have enough remaining frets left afterward (Mind you, I do have a 'fretless wonder' Gibson LP here, so will manage LOL).

The quality of the workmanship on the body and neck otherwise is very good and I wouldn't hesitate to order again from Pitbull.
The HW is as expected with a kit and easily swapped out. (I opted for some upgrades, but will likely upgrade further to some parts I already have here anyway).

I think I may order another and make a Van Halen Shark next But best get this one done first.

Thankyou and regards,
G.
