I feel your quandary. I’m in the same boat. I’ve looked at the pros and cons as well. I have x3 Siege seekers and will likely stay with them. I do like those F15 alt modes but not enough to splash the cash for that two pack. Will we actually get them in the UK? It was a mission for me getting Ratchet which I imported from the US and total cost came in at £50 spent. Ironhide I got for £20 which wasn’t too bad for the same mould.
