Having owned the 98 reynolds 631 kila and absolutely loved it, now fancy owning the 98 Explosif. I believe it was only one year they did the 853 version?
...I know we've spoken but for context; my brother has an original early 631 killa and its a lovely ride; the difference between this and 853 is the latter has more zing and to my arse greater comfort...its a hard to define ride but close to Titanium to me?
I think it depends on a few things, tyres saddle etc. I preferred the ride of the 98 kila to my current rocky blizzard... And I had an early ti litespeed... And got rid of it, didn't like it... for me it's steel over ti
