Nope. Had a HL 5 Spot and now a DW 5 Spot. Fantastic bikes. Would like to try a Ventana, they look beautifully built frames. Try over at MTBR.com, bound to be someone had/tried both.

I'd say bushings as Turners come grease ports on all the pivots to keep 'em topped up. My HL 5 Spot was over five years old and was only on its second set of bushings. Like I say, no experience of Ventana's, so don't know how the bearing last.

06' El Ciclon here. Not ridden a 5-Spot.
Had a Brain-Shocked Enduro before. Compared to that the Ventana has very active suspension. Certainly a more supple ride, not wollowy/bouncy, just very smooth. I tend to ride mostly with the ProPedal on & knock it off for descents. Very very stiff frame, no noticeable flex at all.
In honesty it has way way more ability than I have. Coil Pikes up front, running at 130mm most of the time.
Build quality is good, first glance it doesn't grab you, but look closely & there's lots of small detail. Excellent paint also.
As above with being easy to service. Frame is in bits in minutes, literally. Mine still on original bearings, AFAIK.
Bought mine S/H off here. Only downside is having to remove the upper shock bolt to add air, was sorted on the 08' on I think, (different shock top end).

Medium.

Good. Has 2.35 Kendas on at the moment, bit draggy now the Chase is a mud pit. Might go to 2.1's for the Winter.
keep an eye on THIS FlickR set, I'm just uploading some more pics now.

I have owned both bikes and like the turner better. The DW set up is better than what the ventana has. The ventana can bob a bit without the propedal on.

Try both out

same as John, in that I have owned both: I had an el ciclon and now ride a DW spot. Both are fantastic rides, up and down, but the spot is more lively (in a good way), in terms of climbing and acceleration – it makes me feel fitter than I am. On descents, both make me feel braver than I am. And I'd agree with Chucky that Alan at Riverside is great to deal with. The bearings on the ventana lasted fine – survived two years of wet and muddy lakes riding without complaint.

eenie meenie minie moe…

Had both.Ventanna had a far better paint job and the finish was of a higher standard.Because the V is so stiff in the frame and with the quad bearing option,the bearings last for eva.There is more bob with the V but also less feedback thru the peddles and i thought it was a more supple system.The T peddled better but there was a level of kickback on some big hits.Both fantastic bikes and really this is splitting hairs.For me the V had just a little bit more of the boutique feel and look.
