Crispy and CT Girl....love your deductions, a logical way to figure out the losing tribe. But, beware. Crispy, many times teams that are way behind end up winning challenges with good puzzle solvers. I don't think we can assume at all that Matsing loses this because Angie is a puller.

Another thing regarding your deductions, CT Girl, we have vidcap evidence of Angie pulling with Russell while it's Jeff/Carter and Mike/Pete. But we also have vidcap evidience that perhaps some of the guys pull the sled in retrieval of the first and third tables with puzzle pieces while a different group may take up pulling the sled in retrieving the second/middle table puzzle pieces....

Here is a picture of Roxy pulling, perhaps...

Here is RC pulling the sled...

Here is Russell pulling the sled...

so, here is what CTGirl posted and I have added my 2 cents in bold:

Kalabaw
Dawson sits out
Carter and Jeff we see pulling
Katie is probably the caller from the vid cap above
Penner and Dana? Penner probably does the puzzle with Katie, but likely does the pulling of the sled to retrieve the middle table contents

I agree, Penner is likely a good puzzle solver....don't know about Dana, nor do I know how well Katie will do as the caller. The fact that we see Penner searching all over the camp makes me think that they could lose the IC

Tandang
Abi sits out
Mike and Pete pull for the first and third retrieval, while RC and Artis pull for the 2nd table retrieval of pieces
Lisa calls
RC and Artis most likely will be puzzle solvers with Lisa at the helm.

Matsing
Russell and Angie pull for the first and third heat, Roxy pulls with Malcolm for the second heat
Denise calls
Malcolm and Roxy? Malcolm must pull and Roxy solves. It doesn't make any sense otherwise. I think both Malcolm and Roxy solve

Regarding puzzle solving...Malcolm is an Ivy League graduate and most likely is a good puzzle solver and I would bet that Denise is excellent, and Denise will be the one to call the shots, and I think Malcolm would let her lead....in other words, they most likely will work well together.

I have a suspicion that kalabaw may lose the challenge...? And, if they suspect Penner has the HII, who would be most likely to be sent packing? We know Dana is in a future challenge, so it would have to be either Katie or Dawson...
