THat is good to know BikeSkiRun.
Thirtysomething, i have had a go on the BJCS. i took it for a spin around John Lewis with DD in it at the time and got on very well with it. I have seen a few around town as well and have actually stopped the owners to ask how they were getting on with it. Without execption the response has been positive. THe thing i liked best about it was the second seat was up high enough that i didnt have to use the shopping basket as a foot well and i could still hang my changing bag off the handlebars without clocking whoever was in the second seat in the head.
I loved the Sport when i first got it for DD1 but it drove me mental that it was so difficult to raise the back of the seat from lie flat to upright etc without taking the baby out. Doing it with the baby in it is outright impossible i beleive. The back is raised by securing various clips and zippers. THe Zippers are ok but i defy anyone to get the bottom clip done up while a child is in the seat. Apparently it is made that way so that any child in the rear seat cant collapse the front seat onto themselves. Makes sense but god it was annoying. The BJCS has very easy to recline seats with no clips or pulleyr or zips.
I also hated that fact that when DD was in lie flat mode gettign access to the basket basically requied me to get down on hands and knees. This stuff never occured to me when i decided to buy one but drove me bonkers once we actually started using it. From my experimentation i could access the BJCS basket from all angles and all seat positions.
I was also not happy that i would lose the shopping basket once DD1 was in the back seat. That might have been more of an issue for me than others though as DD1 has ridiculously long legs and wont stop growing. I could forsee grubby feet all over my changing bag/snack bag/shopping. You can get panniers that fit onto the side of the buggy to compensate but then it seems to me you lose the value of an inline buggy.
I also found that with the second seat attached to the Sport i would scuff and kick it as i pushed. I am 5"8 so not THAT tall. My H is 6"1. It would have driven him mad (he hated my zippy P&T Smart for that reason). THe BJCS has a height ajustable handle and on its longest extension was more than adequate for DH.
I also wasnt dead keen on the fact that as i understood it DD2 would be in the lie flat mode with DD1 basically sitting on top of her on the second seat but that was based on me beleiving that you couldnt have baby in carseat in the main seat and toddler in the rear seat. That was pure preference though. It just seemed so small and claustrophic and airless in there. As i am expecting a late spring baby i was a bit concered about baby getting too hot.
THe BJCS has roughly the same footprint as the SPort/Explorer but i think it is better designed at least for my needs.
Having read back what i have written i can see that it looks like i hate my SPort. I really dont. It is a great buggy that is easy to to put up and put down, goes anywhere and does it well. It has travelled with me to Oz and across Europe and survived everything we have thrown at it from sandy beaches to forest trails and it still looks great but for my needs now i am taking the opportunity to get something that will i beleive do all that and do it without the annoying niggles.
