woohoo, finally a Titan user! Thank you so much for your analysis.
yes, in fact, i am currently considering Tein Flex or Titan :P There is one set of Tein's on sale, but you know, second hand unit, can't really be 100% sure. If it leaks again, then i'll be back to my current setup :P
I got it serviced at my regular mechanic. Unfortunately, after servicing, it will cost additional to readjust the stiffness of it, so i just leave it. Hoping to save up for a set of new shocks instead. I wouldn't recommend getting yoru Tein's serviced by an independant party. Better spend a bit more and send it to N1 who are the authorized service centre.
when i was using the Tein HA, i seldom adjusted it anyway. In fact, i think its because of my adjustment ( making it stiffer ) which caused it to leak! and once it leaked, it was as soft a butter :P
for me, i would prefer a comfortable ride compared to horse riding. I am not a track person, at least not with the mr2 :) , so i do not need super hard suspension for cornering.
Again, thanks for your comments, i'll consider Titan more favourably now :)
cheers!
